Anyone know how to view or delete this blank directory?

Hi,

have you tried to use the graphical file manager?

I assume it is this one?
drwxr-xr-x 2 oracle oinstall 96 Feb 23 2007

You need to use "ll -b" to see the unprintable chars. If you can type those chars, you can use mv(1) to rename it.
Otherwise you may have to move everything else out of the directory and try using "mv * dirname" to rename it. (Provided "*" is replaced by one name.)

Hi,

You can use the rm -i * command and just run through answer 'n' to everything except your magic blank directory.

Hi,

Search for the inode and use find to remove the directory.

$ mkdir " "
$ ls -li

Get the inode num of the blank directory using ll(1) and then use find(1) with the "-inum" switch to remove that blank dir as follows:

# ll -lbi
# find . -type d -inum -exec rm -rf {} \;

Re: Blank Directory name

Geoff Wild — Tue, 27 Nov 2007 12:12:51 GMT

ls -il

That will give you the inodes...

Then:

find . -inum 555555 -exec rmdir {} \;

where 555555 is the inode of the directory with no name...

Reminds me of that song...been to the desert on a horse with no name...

Sometimes I find that there are unprintable characters in the filename. Do the following

ls -l >>file1

Edit file1 with vi so only the filename is there.
To check do

ls -la `cat file1`

If this works then
rm -r `cat file1`

Hi:

Be advised that inode numbers are only unique within a filesystem! Hence, you would NOT want to do:

# find / -inum 1234 -exec rm -rf {} \+

...since this would destroy every file or directory with an inode number of '1234' in EVERY MOUNTED filesystem (i.e. '/var', '/usr', etc.)

Instead, do:

# find / -xdev -inum 1234 -exec rm -rf {} \+

...to CONFINE the search to the filesystem specified.

For that matter, it is good practice to impose an interactive remove like:

# find / -xdev -inum 1234 -exec rm -ri {} \+

...to be safe.

Regards!

...JRF...

ensure you supply your local directory to the find command when searching for/removing inodes.

find /local/oracle -inum ...

Also, before you -exec rm -rf, just execute the find command to list the files/inodes it finds to avoid deleting files by mistake

Dennis Handly — Tue, 27 Nov 2007 22:30:21 GMT

Instead of trying to remove it, the first effort should be trying to rename it as Volkmar and I have suggested. That way you don't have to do all of these complex finds.

If your directory has a space, you can simply quote it. Once I had a file with a DEL. I simply typed that, since DEL isn't special for my shell setup.
